Provides access to API used to encode and decode bitmap images.

 说明
公共类BitmapCodecInfoProvides information about a given codec. This is an abstract class.
公共类BitmapDecoderRepresents a container for bitmap frames. Each bitmap frame is a BitmapSource. This abstract class provides a base set of functionality for all derived decoder objects.
公共类BitmapEncoderEncodes a collection of BitmapFrame objects to an image stream. This is an abstract class.
公共类BitmapFrameRepresents image data returned by a decoder and accepted by encoders. This is an abstract class.
公共类BitmapImageProvides a specialized BitmapSource that is optimized for loading images using Extensible Application Markup Language (XAML).
公共类BitmapMetadataProvides support for reading and writing metadata to and from a bitmap image.
公共类BitmapMetadataBlobProvides a placeholder for metadata items that cannot be converted from C# to an underlying data type that persists metadata. The blob is converted into an array of bytes to preserve the content.
公共类BitmapPaletteDefines the available color palette for a supported image type.
公共类BitmapPalettesDefines several color palettes that are commonly used by bitmap images.
公共类BitmapSizeOptionsDefines size-related attributes of a cached bitmap image. A bitmap is scaled based on values that are defined by this class.
公共类BitmapSourceRepresents a single, constant set of pixels at a certain size and resolution. This is an abstract class.
公共类BmpBitmapDecoderDefines a decoder for bitmap (BMP) encoded images. This class cannot be inherited.
公共类BmpBitmapEncoderDefines an encoder that is used to encode bitmap (BMP) format images.
公共类CachedBitmapProvides caching functionality for a BitmapSource.
公共类ColorConvertedBitmapChanges the color space of a BitmapSource. This class cannot be inherited.
公共类CroppedBitmapCrops a BitmapSource. This class cannot be inherited.
公共类DownloadProgressEventArgsProvides data for the BitmapSource.DownloadProgress and BitmapDecoder.DownloadProgress events.
公共类FormatConvertedBitmapProvides pixel format conversion functionality for a BitmapSource. This class cannot be inherited.
公共类GifBitmapDecoderDefines a decoder for Graphics Interchange Format (GIF) encoded images.
公共类GifBitmapEncoderDefines an encoder that is used to encode Graphics Interchange Format (GIF) images.
公共类IconBitmapDecoderDefines a specialized decoder for icon (.ico) encoded images. This class cannot be inherited.
公共类InPlaceBitmapMetadataWriterEnables in-place updates to existing blocks of BitmapMetadata. This class cannot be inherited.
公共类JpegBitmapDecoderDefines a decoder for Joint Photographics Experts Group (JPEG) encoded images. This class cannot be inherited.
公共类JpegBitmapEncoderDefines an encoder that is used to encode Joint Photographics Experts Group (JPEG) format images. This class cannot be inherited.
公共类LateBoundBitmapDecoderDefines a decoder that requires delayed bitmap creation such as asynchronous image downloads. This class cannot be inherited.
公共类PngBitmapDecoderDefines a decoder for Portable Network Graphics (PNG) encoded images. This class cannot be inherited.
公共类PngBitmapEncoderDefines an encoder that is used to encode Portable Network Graphics (PNG) format images. This class cannot be inherited.
公共类RenderTargetBitmapUsed to convert a Visual object into a bitmap.
公共类TiffBitmapDecoderDefines a decoder for Tagged Image File Format (TIFF) encoded images. This class cannot be inherited.
公共类TiffBitmapEncoderDefines an encoder that is used to encode Tagged Image File Format (TIFF) format images.
公共类TransformedBitmapScales and rotates a BitmapSource. This class cannot be inherited.
公共类WmpBitmapDecoderDefines a decoder for Microsoft Windows Media Photo encoded images. This class cannot be inherited.
公共类WmpBitmapEncoderDefines an encoder that is used to encode Microsoft Windows Media Photo images.
公共类WriteableBitmapProvides a BitmapSource that can be written to and updated.
